The 89th annual Macy's Thanksgiving Day Parade starts tomorrow morning, but one of the major highlights of the event happens the night before. Some people are lucky enough to live in the city, or are able to trek to New York, to witness the inflation of the iconic balloons that soar through the skyline during the parade. The streets surrounding the Museum of Natural History were packed with thousands of people coming to witness the balloons up close, and to see the hundreds of volunteers it takes to make the magic happen and bring these deflated balloons to life.

This year has 24 balloons featured in the parade with a few new ones, including a new design of Ronald McDonald, the red Angry Bird, Scrat and his acorn from "Ice Age" and DINO by Sinclair Oil - a comeback balloon from over 40 years ago - which is actually the only life-sized balloon in the parade. The balloons line the streets all night, hidden under rope nets until the morning when they are set to take to the air.

The iconic Macy's star balloons signal the start of the parade.

Hello Kitty returns again this year as a popular favorite.

Each balloon has a team of approximately 20 people to help inflate and control the balloon the day of the parade.

The balloon flight management team consists of one pilot, two co-pilots, one captain, two assistant captains and a team of people that control the movements of the balloon.
